Title: Semiconductor laser connector for single mode optical fiber
Inventor: SARUWATARI MASATOSHI
IPC: G02B6/42
Filed: 1979-05-19
Abstract: PURPOSE:To improve the manufacturing property of the lens and to relax the set errors with an increased focal range of the lens by forming a tapered section in such a manner that the core diameter lessens gradually toward the tip while the difference in the refractive index remains unchanged at the light incidence section of the optical fiber. CONSTITUTION:The output beam from the semiconductor laser 1 converges on the single mode optical fiber through the cylindrical lens 2. The core 5 of the single mode fiber is so arranged in the incidence section of the optical fiber 3 in the semiconductor laser connector that the diameter thereof reduces toward the incidence end to form a tapered section 6 on the core 5 of the single mode fiber. The tapered section can be set at the optimum shape by the lens 2. This increases focal distance of the lens and facilitates the manufacture of the lens 2 thereby relaxing the set errors of the lens 2. Another example shows that the construction of the connector can be simplified by fastening the lens 2 to the light incidence face of the fiber 3.

Filed: 1993-02-25
Abstract: PURPOSE:To facilitate machining of a slider rail having complicated shape by subjecting a conductive slider material to electrical discharge machining using a discharge electrode having a desired shape. CONSTITUTION:Voltage is applied between an electrode 12 and a supporting base 14 of an electric discharge machine 10 and then the electrode 12 is lowered to start discharge with respect to a conductive slider material 13. Consequently, discharge takes place at a patterned protrusion provided on the plane of the electrode 12 opposing to the material 13 and the opposing part of the material 13 is shaved thus transferring the pattern of the electrode 12 to the material 13. The material 13 is then sliced to produce a slider. This method allows machining of slider rail into an arbitrary shape thus allowing manufacture of a slider having rail shape excellent in floating characteristics.
